[0002] The bridge building shock-absorbing bearing side support steel casting is a shock-absorbing element specially used in bridge construction. It is usually made of high-strength steel and undergoes precision casting and processing. The main function of this steel casting is to reduce the vibration and deformation of the bridge structure under the action of earthquakes or other external forces, and improve the seismic resistance and safety of the bridge.

[0003] As the bridge structure vibrates, the shock absorbing device will exert a vibration force in a direction with a certain offset angle. During this force application process, the center of gravity of the shock absorbing device will shift, causing damage to the internal structure of the shock absorbing device.

[0004] In response to the above problems, the utility model provides a steel casting for a bridge building shock-absorbing support with a center force direction adaptive. The application adopts a support structure with a central sphere shock-absorbing buffer, which alleviates the vibration force received by the shock-absorbing support in the offset direction through the sphere shock-absorbing structure, and can prevent the support from being broken or separated internally due to offset during the shock absorption process.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] like Figure 1 , Figure 2 As shown, a steel casting for a bridge structure shock-absorbing bearing includes a top plate; the top plate 1 is integrally connected to an upper cover 2 at the bottom center, a spherical groove is retained in the center of the upper cover 2, the groove is fitted and contacted with the upper part of the balancing ball 3, the lower part of the balancing ball 3 is fitted and contacted with the groove at the top of the lower cover 5, the lower cover 5 and the ring piece 9 are in an integral connection structure, and the ring piece 9 is clamped between two groups of clamping plates 7. The upper cover 2 is affixed with a wear-resistant layer 13 along the contact end surface of the balancing ball 3. The two groups of clamping plates 7 and the ring piece 9 are vertically connected by mounting bolts 8. Among them, the upper cover 2 is used as a top load-bearing structure to transmit the vibration force to the lower cover 5 through the balancing ball 3. In this process, the balancing ball 3 can adapt to the force in the horizontal direction to cooperate with the upper cover 2 and the lower cover 5 to perform an offset rolling process. The ring piece 9 is an integral extension structure connected longitudinally, and cooperates with the two groups of clamping plates 7 to complete the clamping and positioning process.

[0021] like Figure 1 , Figure 2As shown, the top plate 1 is equipped with four sets of sling mechanisms 4 along the outer side of the upper cover 2, and the bottom sleeve 12 of the sling mechanism 4 is connected with the mounting bolt 8. The sling mechanism 4 is designed as a buffer structure for the second swing deviation.

[0022] like Figure 1 , Figure 2 As shown, the sling mechanism 4 includes a chain rope 11, an insertion shaft 10 and a sleeve 12, and the chain rope 11 is connected between the upper and lower sleeves 12, and the insertion shaft 10 is inserted in the center of the sleeve 12. The sleeve 12 at the top is connected to the bottom end surface of the top plate 1. Among them, when one or more of the four groups of chain ropes 11 are subjected to force, the opposite side will limit the swing of the upper cover body 2 through the dragging force, so as to avoid excessive swing of the structure and failure to operate normally.

[0023] like Figure 1 , Figure 2 As shown, a guide shaft 6 extends vertically downward from the bottom center of the ring sheet 9, and the guide shaft 6 extends out along the central through hole of the clamping plate 7 at the bottom position. The guide shaft 6 is used as a fixedly installed limiting structure.

[0024] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
